The vertebral body structure as well as the whole body and nerve injury after treatment of thoracolumbar fractures through paraspinal muscle approach and traditional approach

摘要

Objective:To study the vertebral body structure as well as the whole body and nerve injury after treatment of thoracolumbar fractures through paraspinal muscle approach and traditional approach.Methods:A total of 74 patients with thoracolumbar fractures who received surgical treatment in our hospital between September 2013 and October 2015 were selected and randomly divided into the paraspinal approach group and the median approach group who received the internal fixation surgery through paraspinal muscle approach and the internal fixation surgery through traditional median approach respectively. Before surgery as well as 3 months, 6 months after surgery, Cobb Angle was detected; before surgery as well as 1 d and 3 d after surgery, serum levels of creatase, stress hormones and nerve injury molecules were determined.Results:3 months, 6 months after surgery, the Cobb Angle of paraspinal approach group and median approach group were significantly lower than those before surgery and the Cobb Angle were not significantly different between the two groups of patients; serum LDH, CK, Myo, NE, E, Cor and Ins levels of both groups 1 d and 3 d after surgery were significantly higher than those before surgery and the serum LDH, CK, Myo, NE, E, Cor and Ins levels of paraspinal approach group were significantly lower than those of median approach group, serum NSE, S100B and GFAP levels of both groups 1 d and 3 d after surgery were significantly lower than those before surgery and serum NSE, S100B and GFAP levels of paraspinal approach group were significantly lower than those of median approach group. Conclusion: The vertebral body stability are equivalent after treatment of thoracolumbar fractures through paraspinal muscle approach and traditional approach, and the trauma extent of paraspinal muscle approach is less.
